This last 12 months have been intense and exciting and what
a lot of changes this blossoming industry has seen.

Things I’m glad I got on and finished – (is anything ever finished?)

Universal paste and Chocolate printing, I had been thinking
about this for well over a year before actually starting any testing, it was a
good learning curve in 3D design (Sketchup) and iterative model testing.

If you have not yet seen the wonderful video by RepRapBCN, take a look below!

The 3way extruder – Colour blending, lots of further potential, great fun
doing it and seeing the first prints.

Joris Van Tubergen also made a 3 filament extruder, but his goal was to be able to extrude more filament for the amazing Kamermaker project his aim is to be able to extrude 1kg and eventually 5kg/hour of plastic.

Other translations of my Slic3r tutorials and extended work
can be found in Portuguese, Russian, Spanish and Italian. - if you know of more do let me know.

Slic3r continues to move on and get stronger with more
people using it every month.

If we had 3D printing awards Slic3r would get my vote for
first place. My warmest thanks go to Alessandro for bringing Slic3r to all of
us.

30 Days of creativity – Was hard work, but a very good focus
for getting things started and having some fun with my printer.

I have really enjoyed printing more things for my kids this
year, they love them!

It’s certainly easier when you have more than one printer up
and running.

More group meetings with local RepRappers – it’s been a great year for getting people up and running.

Things I have not finished quite yet –

Geared Peristaltic Pump – I have grand plans, and it's working so well but it’s going to take
more time before I can get back onto this. Keep an eye out on this development, I'm planning a dedicated printer to use it for something interesting.

Ceramic Printing, I had all the best intentions to do more
ceramic printing, Precious metal clay printing and ‘other’ materials, but just
not had the time to set it up again and have a good run at it. – When I think
back I did the whole paste extruder development in about 2 weeks. - New 'RepRap year' resolution - 'find, use and develop more materials to 3D print with'

Further rounds of Polycarbonate printing, I started and then
got side-tracked. I’ll pick it up again at some point along with other sorts of
materials (Like Laywood).

My own machine development – Again started, many things
worked out, but everything moves so fast it always needs a little rethink.

My design looks a little like the TK-O from LulzBot (Aleph objects),
so I may take some more inspiration from that to finish-off my 'ultimate 3D
printing machine'.

Recent time has been taken up with Rostock (see below) so what I learn from that and seeing how the TK-0 develops can go into the next revision

Rostock+,
doing it now, but stalled a little for the last 6 weeks, need to build some more
electronics.

The ‘Plus’ part is for the use of Spectra fishing line (Like Tantillus below) instead of
belts and pulleys, should look cool and be FAST!

More tutorials and guides, I have started some, it’ll be
easier to focus on them in the winter, but I want to make it easier for people
to get good 3D printing results and understand more things about the process.
> Still learning every day myself!

Things I wish I had more time/resources for –

Actual 3D modelling and design, I’m planning to spend more
time over winter doing 3D design and modelling, some organic and creative,
other things more technical.

I want to learn Autocad123D as I have failed to spend any
time with it this year – if anyone knows any good starting guide? – I have not
really used the Autocad interface and I find it quite counter intuitive.

I have been inspired with so many works of 3D printing
Art this year, far too many to mention, but ones you should really take a look at are the beautiful works by @Dizingof , the mechanical wonder of the planetary gears by aubenc and very stunning Trilobite’s! by AuntDaisy

I love to print tricky models, it takes time to work out the
best settings and it’s often different for each complex object, but hopefully
we will continue to do challenges – they are a great way to learn ‘how to 3D
print’

I do wish I had more time to meet more of the 3D printing
community; we need a few more places to meet up during the next year. Any
ideas? maybe video links?

Visiting more printing events and shows, they are great, but
take time and money to attend. And are not very family friendly L very disappointed I could not make the London3Dprintshow and the 3D printing event in Eindhoven, but I did make it to a few events.

I also didn't use IRC as much as I wanted, started off the
year using it, then also started on Twitter and didn't have the time to do both
along with doing actual physical developments of things.

But I’ll get back on IRC soon, it’s a great community.

I answer a lot of e-mails and messages, and try to help
people as much as I can, recently the RepRap forum has boomed with new people
and questions; it’s hard to keep up!

I started a dedicated website (richrap.com), with the idea to show projects, tutorials, guides and general RepRap related developments. It needs more
time spent on it, but it’s a start.

Software development, I should spend more time refining some
of my developments (3way extruder to be automatic, more firmware integration) I
need enough long periods of time to focus on it.

Things I have not started yet (but are on my list) –

Electronics – I was sure I would have time to do some real electronics
development this year, but again so many new boards popped up, my own plans didn't need as much attention as I had thought- still we are some way off a
real plug and play solution.

A really big printer! – I really wanted to do something like
the Kamermaker (room builder) - cost, space and time just let me down, but I
still have a vision for something not quite as big...

Concrete/cement printing – I’m seriously thinking about a good way to
do this - anyone want to help me make it a reality?

Loss wax casting (with PLA) – Some good examples this year,
would love to give it a go.

Resin printing – Almost got motivated to start on a LemonCurry, again didn't get time past reading all about the great project. –
Interesting to see the Formlabs printer using a Laser and Resin just got over
$2.9 Million on Kickstarter, Wow!

Experimenting with new support materials – I did just start doing this, some interesting results with sugar, needs a lot more work, Sugar seems
very compatible with PLA.

Wax printing – Still not sure how best to move forwards with
this – maybe try a new design of my heated universal paste extruder, it should
work.

A Portable 3D printer - I still don’t have a true
portable printer (folding or just easy to carry) – finishing Tantillus is my best option
for the moment.

Lasers! – Powder and Sintering – I doubt I’ll be able to
work on this area anytime soon! But it’s on the list!

I would still like to buy a new Lathe; still saving up…a few
people have offered to help me out with new things needing machining – Thank
you.

+++ Lots of stuff I have not even thought of yet !

Final thoughts -

So, I have had some real proud moments in my 2012 RepRap developments;
I have had fantastic people from all walks of life contact me. My work has been
featured on lots of blogs and in magazines, interviewed, mentioned and cited in
reports and academic works. I have done presentations and uploaded work and videos to
university intranets and had people translate my projects into different
languages.

Thank you all.

This is all open-source and as a hobby on a very teeny tiny
budget, and I’m just one of many makers doing lots of things in this Great
community.

The next development cycle has now started, I have some big goals for the next 12 months, no one knows where 3D printing is heading, and what it will look like in a further year, but it will continue to be exciting.

If you can make it, come and join us at Cheltenham Geeks in November, It's free but with limited spaces, go and register now over at meetup.com. Hamish and I will be presenting an evening of RepRap fun and developments, along with 3D printing demo's and beer, what more could you want?

Thanks for reading; I hope you are enjoying the adventure, See you soon for more.
